2008 Subaru Impreza WRX has 224 hp..cheap turbo to bump up 265hp?

Is there any cheap used STi's turbo that will bump my HP to about 265? I'm disappointed that the 2008 wrx has a smaller turbo which runs only 224hp... I'm looking to spend a few hundred bucks if possible...and I'm not looking for a GT35R or anything huge, just enough to bump my horsepower 40-60hp.

So you can't just slap on a 2008 WRX STi turbo? I would purchase a downpipe and a accessport as well...

I saw the STI turbo on ebay for 2008 used for $300.. The fittings aren't the same? I thought the 2009 WRX was the same way, they just put a STI turbo in it.

Dez already answered this. You can't just slap a different turbo on, you'll need a custom tune. That is different than using the accessport's pre-loaded maps. If you look at Cobb's website they clearly state in the map notes what the tunes on the ap support.

Basically what everyone is saying is that, with a bigger turbo you will need fuel upgrades and a tune. If you don't understand why this stuff is needed there are plenty of threads and stickies explaining it. I don't know about newer generations, but you may need an intercooler upgrade as well.

The car is a whole system and when you change a component in a system, you will need to change other components etc. The STi turbo will likely bolt up and fit physically, but you will need to upgrade other things in order to "support" it.

The better route, like everyone has said before is to get a tune and a downpipe. That will get you to your power goal.

VF52... Not a cheap turbro unless found used. Other than a tune, you'd be good to go.
Of course, to be completely safe and sound, fuel upgrades should be had, but a moderate tune would not necessitate them.

I had an '08. All I did was put on a CBE, CAI and got a tune by someone who knows what they're doing. I gained minimal HP, but TONS of torque. At the wheels it was only 191HP...but the torque was at 290TQ (Mustang AWD Dyno). We pushed the turbo to 16.9PSI peak. It was plenty faster and very cost-effective and NO CELs or other issues in over 4 years. Smaller turbos usually mean less turbo lag as well. I had virtually NONE...instant power off the line. Just sayin'...

Not even, the 08+ have a LGT style turbo, so a STI turbo won't just fit regardless of the year.

Do as others advise, downpipe and a tune. If you feel it's still lacking, get a VF52 (09 WRX turbo) with supporting mods.

The 08+ what? The 08+ WRX's have an LGT style turbo whereas the 08+ STi's do not?

02-07 WRX and STi have the same turbo "styles" so they will exchange. I only know 02-07's. I was just making a conjecture. But the main point was that he would have to do supporting mods to upgrade turbos.

Motor trend says that the 2009 WRX turbo is the STi turbo. Also, I mean't I would use the cobb tuning accessport for the down pipe. Unfortunately, I don't wanna even support this forum no longer due to the amount of douchebags on here.
